The Government of Canada issued a rfp for the transport of two Mid-Shore Patrol Vessels (MSPVs), each 42.8 metres long by 7 metres wide and each of 265.8 tonnes displacement, aboard a larger vessel with heavy-lift capability.
This one-way transport voyage, carrying two Canadian Coast Guard vessels is expected to commence in October 2014 from Halifax, Nova Scotia, on the Atlantic coast of Canada, arriving at an international port, closest to Victoria, British Columbia
The Mid-Shore Patrol Vessels (MSPVs) were built to replace aging CCG vessels patrolling Canadian waters on both coasts and in the Great Lakes.
The last two MSPVs in the series of nine, to be built under Contract for CCG by Irving Shipbuilding Incorporated in Halifax, Nova Scotia, will be based in Victoria, British Columbia.
The Contract with the Ship-builder does not provide transport for any of the nine Mid-Shore Patrol Vessels to their eventual destinations.
Heavy-lift transport of the two MSPVs was only one of the options investigated; others such as sailing the ships on their own hulls were researched to determine what option was the most cost-effective;
Sailing the MSPVs on their own hulls would seem to be cheapest method of transporting, but these small vessels are only allowed to travel up to 120 nautical miles off the coastline and MSPVs only have a maximum range of 2000 nautical miles. By following the shape of the coast closely and entering a number of harbours to re-fuel along the coast, this strategy can add up to 800 Nautical Miles to the length of the voyage and more voyage costs than a larger vessel would incur, such as harbour fees, pilotage fees, fuelling and provisioning costs. The time taken to sail this additional mileage will increase the delivery time to the final destination. Larger, heavy-lift commercial vessels do not have the same voyage restrictions off the coast as MSPVs; therefore they can use more direct, shorter routes and make less port visits, which cuts the time and costs needed to deliver both MSPVs to CCG - Pacific Region.
Since there are few, if any, Canadian heavy-lift vessels capable of performing this transport, most likely an international shipper will be using a foreign-flagged vessel to complete this Contract work. Shipping cargo from a Canadian departure point, aboard a foreign heavy-lift vessel means that there are Canadian Cabotage Law considerations and potential tariffs at the destination; To avoid punitive tariffs most shippers would recommend the use of the closest U.S. sea-port to Victoria, B.C., such as Seattle, Washington, to be their destination.
